I just replaced my PVC bunks to 3" and wanted to know if you all had a preference? My second try was hugely improved over my first ones, hopefully this time my hardware won't come off... Ill try to post pics later...

I used 2 inch on the original design because it fits the hull troughs better. It's also more flexible and conforms to the hull easier, which is what I was after when I came up with the idea.

I'm sure other sizes can be successfully employed.

Thanks for the reply Tom. I really appreciate all your videos on YouTube. I will soon be changing my trailer setup to mimic your rig to hold 2 PAs. One more question, how do you rig your bolts? Do you apply loctite? Do you do two nuts?
